Factors influencing the use of clinical guidelines by general practitioners working in a setting of complex multimorbidity: a case study by interviews.

BACKGROUND: The Central Australian Remote Practitioners Association Standard Treatment Manual (CARPA) contains protocols for primary health care in remote Central Australia. This context stands in stark contrast to the mainstream settings in Australia and features an Aboriginal population with very poor health status, powerful social determinants of health, geographical isolation and high turnover of health practitioners. The manual consolidates the core elements of national guidelines, particularly as they pertain to Aboriginal health care, into a single document. The aim of this study is to explore factors that promote or impede the use of CARPA by general practitioners (GPs) in Central Australia, with a particular focus on chronic disease management. METHODS: In-depth interviews were conducted with GPs and GP registrars employed in the provision of Aboriginal health care in Central Australia. Interview transcripts were thematically analysed from a critical theory perspective. RESULTS: 11 GPs and 3 GP registrars from the two major Aboriginal primary health services in Central Australia were interviewed. The dominant theme in the data was that poor continuity of care impeded the use of CARPA. The second-most dominant theme was that electronic health record systems enhanced the use of CARPA in some ways, and impeded its use in others. Other factors influencing the use of CARPA included the culture of the health service organisation, GPs' first impressions of CARPA, the accessibility and usability of CARPA, and GPs' confidence practicing in such a unique environment. CONCLUSIONS: This study identifies factors from multiple domains that influence the use of best practice guidelines in the delivery of chronic disease care. It demonstrates that such factors may not be purely 'enablers' or 'barriers', but may be a mixture of both. It highlights the critical role of continuity of care and the potential benefits and pitfalls of using electronic health records in providing chronic disease care. This study provides empirical insights that can be used to improve chronic disease care.

Re-orienting a remote acute care model towards a primary health care approach: key enablers.

INTRODUCTION: The objective of this study was to identify the key enablers of change in re-orienting a remote acute care model to comprehensive primary healthcare delivery. The setting of the study was a 12-bed hospital in Fitzroy Crossing, Western Australia. METHODS: Individual key informant, in-depth interviews were completed with five of six identified senior leaders involved in the development of the Fitzroy Valley Health Partnership. Interviews were recorded and transcripts were thematically analysed by two investigators for shared views about the enabling factors strengthening primary healthcare delivery in a remote region of Australia. RESULTS: Participants described theestablishment of a culturally relevant primary healthcare service, using a community-driven, 'bottom up' approach characterised by extensive community participation. The formal partnership across the government and community controlled health services was essential, both to enable change to occur and to provide sustainability in the longer term. A hierarchy of major themes emerged. These included community participation, community readiness and desire for self-determination; linkages in the form of a government community controlled health service partnership; leadership; adequate infrastructure; enhanced workforce supply; supportive policy; and primary healthcare funding. CONCLUSIONS: The strong united leadership shown by the community and the health service enabled barriers to be overcome and it maximised the opportunities provided by government policy changes. The concurrent alignment around a common vision enabled implementation of change. The key principle learnt from this study is the importance of community and health service relationships and local leadership around a shared vision for the re-orientation of community health services.

Syphilis epidemiology and public health interventions in Western Australia from 1991 to 2009.

OBJECTIVES: To describe the epidemiology of congenital and infectious syphilis during 1991-2009, examine the impact of public health interventions and discuss the feasibility of syphilis elimination among Aboriginal people in Western Australia (WA). METHODS: WA congenital and infectious syphilis notification data in 1991-2009 and national infectious syphilis notification data in 2005-2009 were analysed by Aboriginality, region of residence, and demographic and behavioural characteristics. Syphilis public health interventions in WA from 1991-2009 were also reviewed. RESULTS: During 1991-2009, there were six notifications of congenital syphilis (50% Aboriginal) and 1441 infectious syphilis notifications (61% Aboriginal). During 1991-2005, 88% of notifications were Aboriginal, with several outbreaks identified in remote WA. During 2006-2009, 62% of notifications were non-Aboriginal, with an outbreak in metropolitan men who have sex with men. The Aboriginal:non-Aboriginal rate ratio decreased from 173:1 (1991-2005) to 15:1 (2006-2009). CONCLUSIONS: These data demonstrate that although the epidemiology of syphilis in WA has changed over time, the infection has remained endemic among Aboriginal people in non-metropolitan areas. Given the continued public health interventions targeted at this population, the limited success in eliminating syphilis in the United States and the unique geographical and socioeconomic features of WA, the elimination of syphilis seems unlikely in this state.

Indigenous Lifescripts - a tool for modifying lifestyle risk factors for chronic disease.

BACKGROUND: A national chronic disease strategy has been described focusing on health promotion and lifestyle change, screening and evidence based disease management. The Lifescripts resources complement this strategy by focusing on health promotion and lifestyle change. OBJECTIVE: To provide an overview of the role of the recently developed indigenous Lifescripts resources as a tool for health checks and chronic disease prevention and management. DISCUSSION: Effective indigenous health promotion requires appropriate tools for behavioural modification and community engagement. This involves a greater emphasis on the social determinants of health to reduce the barriers to healthy behaviours. The indigenous Lifescripts provide a flexible tool for health care providers in the indigenous health sector to deliver lifestyle related brief interventions that accommodate local community resources and support structures. However, to maximise their potential, a systematic approach to incorporating these tools into practice must be adopted.

Predicting respiratory syncytial virus hospitalisation in Australian children.

BACKGROUND: There is limited information on respiratory syncytial virus infections among Australians, particularly those of Indigenous descent. AIM: This study identifies groups of infants at risk of hospitalisation with respiratory syncytial virus-positive lower respiratory tract infection who may be targeted for prevention with palivizumab. METHODS: Case control study: the case notes of 271 children with cases of respiratory syncytial virus-positive lower respiratory tract infection admitted to The Townsville Hospital were studied for risk factors. Controls were chosen randomly from babies born in The Townsville Hospital during that period. Multiple logistic regression analysis and classification and regression tree analysis were used to identify risk factors. RESULTS: Multiple logistic regression analysis identified birthweight <2500 g, maternal parity and marital status to be independent predictors of hospitalisation with respiratory syncytial virus-positive lower respiratory tract infection. Classification and regression tree analysis identified babies born weighing <2500 g who possessed older siblings to be at highest risk. Single mothers and smoking were additional risk factors. Indigenous babies were significantly more likely to be exposed to all of the identified risk factors. CONCLUSION: Babies born weighing <2500 g (especially with siblings) could be targeted for prevention. All Indigenous babies should be considered at high risk because of their exposure to multiple risk factors.

Cost-effectiveness of respiratory syncytial virus prophylaxis with palivizumab.

BACKGROUND: A monoclonal antibody, palivizumab, directed against respiratory syncytial virus (RSV) has been shown to decrease hospitalisation rates. Because of its expense, the cost-effectiveness of this agent should be determined for high-risk groups. AIM: To determine characteristics of RSV infection in Townsville and the economic feasibility of palivizumab immunoprophylaxis in high-risk groups. METHODS: Cases of RSV-positive bronchiolitis were retrospectively identified. Cases were grouped according to recognised risk factors. The hypothetical costs of palivizumab immunoprophylaxis for infants at risk were calculated. RESULTS: The rate of hospitalisation with RSV-positive lower respiratory tract infection was 22 per 1000 live births but increased to 50 per 1000 among Indigenous babies born weighing <2500 g. The cost of preventing an admission in each of the identified high-risk groups, based on drug costs alone, ranged from AD 69,861 to AD 88,547. CONCLUSION: Palivizumab was not cost-effective in the prophylaxis of RSV in the high-risk group of infants tested here.
